[immodule-qt] Turn the argument of QInputContext::filterEvent() into const

[Kazuki Ohta]

Your indication sounds valid to me.
I was confused by this issue in implementing uim-qt.

Please commit.

> 'QInputEvent' as an improvement). It confuses developers as

> when I comsume the event?"

> To eliminate such confusion, I would like to make it const. It
